Season chicken thighs with salt on both sides.
Transfer 1/2 the chicken to a dry, nonstick skillet over high heat. Cook until browned, about 4 minutes per side. Transfer to a bowl. Brown the rest of the chicken. Let cool to room temperature before cutting.
Combine salsa verde, green chilies, garlic, jalapeno, and cilantro in a blender. Blend, starting on low and finishing on high, until sauce is very smooth and bright green.
Cut chicken into bite-sized pieces and transfer back into the bowl. Combine chicken pieces, accumulated juices, and the green sauce into a pot. Season with cumin, chipotle pepper, black pepper, oregano, and salt.
Rinse out blender with a splash of water and pour into the pot. Mix together and set heat to medium-high. Bring to a simmer; reduce heat to medium-low. Simmer until chicken is tender, depending on size of chicken pieces, about 1 hour. Stir in kidney beans and simmer until thickened, about 15 minutes.
